Upon completion of my undergraduate degree at the University of Exeter in Sport and Health Sciences (2017), I decided to pursue a Masters by Research with the Children’s Health & Exercise Research Centre (CHERC) under the supervision of Dr. Alan Barker and Dr. Bert Bond. During my undergraduate dissertation, I investigated the effects of a 3-day juice diet on metabolic health. This led me to discover a passion for working within the healthcare topic, whereby the research which I am doing can improve our understanding and lifestyle.

The areas in which I am most passionate about are clinical exercise physiology, paediatric exercise physiology and nutrition and through my master’s degree I aim to continue to enhance my knowledge within these areas so that I can pursue a career in this avenue.  Working with CHERC has provided me with the opportunity to be in a professional environment with young people, which through my past coaching experience is the most rewarding and enjoyable group to work with for me.

Research projects

Project Title: Investigating the effects of different types of sugar found in sugar sweetened beverages on blood vessel health in adolescent boys and girls.

Supervisors: Dr. Alan Barker, Dr. Bert Bond

Project Description: During my master’s study, I will be investigating the effects of different sugar types, found in sugary drinks, on blood vessel function in adolescent boys and girls. During this time, I will be using a wide range of techniques including measures of cerebrovascular and macrovascular function in order to assess blood vessel health. Participants will complete 4 conditions of different drinks, with the sugary drinks being representative of what is in a typical sugary drink which children and adolescents consume. This is a novel and important topic which needs to be explored given that adolescents consume eight times the recommended daily maximum of sugar intake from sugary drinks alone.
